- VEHICLE-WHEEL.

Specification of Letters Patent.

. rammed Nov. is, 1906.

To all whom it may concern:

Be it known that we, JOHN M. KERWIN, TAYLOR F. BROOMALL, Jr, and HARRY H. BROOMALL, citizens of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Im rovement in Vehicle-Wheels, of which the ollowing is a specification.

Our invention relates to a new and useful improvement in vehicle-wheels, and has for In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and o eration will now be described in detail, re erring to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation of our improved wheel, a portion thereof being in section, clearly illustrating the construction of the same Fig. 2, a section at the line X X of Fig. 1; Fig. 3, a detail view of the hub.

Referring to the drawings, A re resents the hub of the wheel having the oles B formed around its periphery, said holes being threaded to receive the tubular sections C of the spokes, which may be of an number.

D designatesrods forming t e remaining sections of the spokes, and these rods pass through the caps E, which latter are threaded upon the outer ends of the tubular sections C and have upon their inner ends the plungers I, which fit snugly within the tubular sections, so as to slide longitudinally thereto. These plungers bear against the coil-springs G, located within the tubular sections, and the outer ends of the sections D of the s okes have formed thereon heads H,

which t in sockets formed in the blocks I. The blocks I are set in the groove J, formed in the rim K of the wheel, so as to have a sliding movement therein, and in order that the sections. D of the s okes may follow this sliding movement to a 'ted extent rubber bushings Lare set in suitable holes formed in "the innerperiphery of the rim and surround the sections D, as clearly shown inFig. 1.

In practice the rim may be made in two 'sections, "as shown in Fig.2, and bolted together to facilitate the'insertion of the blocks I and rubber bushings.

From this description it will be seen that a wheel thus made when striking any obstruc tion while traveling over a road-bed will absorb the greater portion of the ,jar which would otherwise be transmitted to the vehicle, the effect being to force the sections D of the lower spokes upward-against the action of the springsG, the rubber bushin s permitting a s ight side movement of all t e spokes except ,those which happen to be directly upon the vertical line when said obstruction is encountered, the blocks I sliding in the rim in unison With the side movement of the spokes.

Our improved wheel entirely overcomes the many disadvantages which have heretofore attended upon the use of the ordinary wheel for motor-vehicles, for when said wheels are fitted with solid rubber tires the shock and vibration transmitted to the body of the vehicle are trying upon the mechanism as well as the occu' ants, and where pneumatic tires are use constant annoyance and expense are occasioned by puncture and other accidents, and when a pneumatic tire is out of repair the vehicle is seri-' the inner section of the spokes, springs 10- cated within the tubes, sections D fitted to slide within the tubes and bear against the springs, heads H formed u on the outer ends of sections D, blocks I in w 'ch said heads are seated, a rim having a groove in which said blocks are fitted to slide, and rubber bushings fitted in holes formed in the rim and surrounding the sections D, as and for the purpose set forth.
